Thermoset body countersink

Abstract

A cutting tool having a thermoset molded body and a method of manufacturing the same is provided. The tool includes a tool body having opposed first and second ends. The tool body includes a cutting portion formed at the first end and a mounting portion formed between the cutting portion and the second end. A thermoset molded body is disposed on the tool body at the mounting portion. The thermoset body has a larger diameter than a diameter of the tool body. A cutting insert is positioned within and extends from the thermoset body.

What is claimed is: 
     
         1 . A cutting tool comprising:
 a tool body having opposed first and second ends, the tool body including a cutting portion formed at the first end and a mounting portion formed between the cutting portion and the second end;   a thermoset molded body disposed on the tool body at the mounting portion, the thermoset body having a larger diameter than a diameter of the tool body; and   a cutting insert at least partly extending from the thermoset body.   
     
     
         2 . The cutting tool of  claim 1 , wherein the tool body is made of a hardened steel, ceramic, cemented carbide, and/or cermet. 
     
     
         3 . The cutting tool of  claim 1 , wherein the thermoset molded body is a thermoset material made of a polymer or epoxy. 
     
     
         4 . The cutting tool of  claim 1 , wherein the tool body has a uniform diameter along its axial length. 
     
     
         5 . The cutting tool of  claim 1 , wherein a length of the thermoset molded body is at least equal to a diameter of the tool body. 
     
     
         6 . The cutting tool of  claim 1 , wherein the cutting insert has opposed ends, a first end of the cutting insert including a cutting edge and a second end of the cutting insert including an indentation or mounting detail. 
     
     
         7 . The cutting tool of  claim 1 , wherein a first portion of the insert is embedded within the thermoset molded body and a second portion of the insert extends beyond an outside surface of the thermoset molded body. 
     
     
         8 . The cutting tool of  claim 7 , wherein the second portion includes a cutting edge of the insert. 
     
     
         9 . The cutting tool of  claim 1 , wherein the thermoset molded body includes a RFID chip therein. 
     
     
         10 . The cutting tool of  claim 1 , wherein the cutting insert is positioned within the thermoset molded body such that at least ½ of the surface of the insert is embedded within the thermoset molded body. 
     
     
         11 . The cutting tool of  claim 1 , wherein a cutting edge of the insert extends from the thermoset molded body. 
     
     
         12 . A method of manufacturing a cutting tool comprising the steps of:
 providing a tool body having opposed first and second ends, the tool body including a cutting portion formed at the first end and a mounting portion formed between the cutting portion and the second end;   providing a mold having a plurality of mold sections;   positioning a cutting insert on the mounting portion of the tool body or secured within one of the sections of the mold;   positioning the mold sections about the mounting portion of the tool body;   introducing thermoset material to the interior space of the mold to form a thermoset molded body around the cutting insert and the mounting portion of the tool body.   
     
     
         13 . The method of  claim 12 , wherein the cutting insert is positioned within the thermoset molded body such that at least ½ of the surface of the insert is embedded within the thermoset molded body. 
     
     
         14 . The method of  claim 12 , further comprising the step of positioning a RFID chip or other component within the mold.
